Implementation Guidelines

• Domain Grouping: Organize code by business domain (e.g., User, Order) instead of framework types.
• DTOs: Use readonly classes to pass data between layers; avoid raw arrays.
• Action Classes: Wrap business logic in single-purpose classes with handle() or execute().
• Repository Pattern: Abstract Eloquent queries behind interfaces for easier testing.
• Dependency Inversion: Bind Interfaces to implementations in AppServiceProvider.
• Model Isolation: Keep Eloquent models lean; only include relationships and casts.

Anti-Patterns

• Domain Leak: No Eloquent in Controllers: Use DTOs/Actions to bridge layers.
• Array Overload: No raw data arrays: Use typed DTOs for structured data.
• Service Bloat: No God Services: Break down large services into granular Actions.
• Infrastructure Coupling: No hard dependencies: Depend on abstractions, not concretions.
